Maintenance support available on Tidelift

I learned that this project is funded on [Tidelift](https://tidelift.com), meaning it's popular enough that it's getting sponsorship money from enterprise customers.

This means that the maintainers of the package have an option to claim the funds in exchange for an agreement to keep the project maintained. I'm active lifter of 28 packages and am excited about what Tidelift is doing to help make open source sustainable.

Given that funding is available, we have a few options (in my order of preference):

- Designate one or two of the primary maintainers (probably @junkmd and @vasily-v-ryabov) to share the income) to register with Tidelift and claim the income. I'd recommend not splitting the income more than two ways.
- I could claim the income and simply oversee the maintenance even though I'm not actively developing the project. I could become slightly more active in the project, but I'd want access to tag releases and adjust repo settings.
- We could simply ignore it and let the project exist unfunded.

Let's discuss and decide what you all want to do. @cfarrow may have an opinion too. I'll be happy to help get anyone enrolled with Tidelift.
